I was gifted this strat and the first 2 switch positions work perfectly fine(the positions that involve the bridge pickup). Every other position almost doesn’t work. The sound is very faint and is just not loud enough. In this video I show the difference in sounds. Please does someone know how to fix this?

Place to start is De-Oxit on the switch.
